Myelination, the process by which glial cells ensheath the axons of neurons in layers of myelin, ensures the rapid conduction of electrical impulses in the nervous system. The formation of myelin sheaths is one of the most spectacular examples of cell-cell interaction and coordination in nature.
The electrolytes in the batteries conduct electricity about one millionth as that of metallic conductors. Non-electrolytes and non-metals conduct electricity less than one-trillionth of that of good conductors in metals. Metals conduct heat and electricity with the help of free electrons in them. When the voltage is applied across the metal, electrons are made to move towards the positive side of the metal. The flow of free electrons will be negligibly resisted and a large flow of electrons takes place.
